Background

• Demographic ageing 19 of the Dutch population
  will be over 65 years of age in 2020, resulting
  in a growing pressure on care institutions
• Shift from standardized mass solutions to
  personalized solutions
• Most people prefer to live independently, in
  their familiar surroundings, as long as possible!

Problem Statement

• Industry recognizes obstacles towards deployment
  of personalized home care services

• Available solutions are non-integrated and
  technology centered and therefore not recognizable

• Current user interfaces are generally complex and
  inherently difficult to use

5
Primary Goal

• ...to develop an integrated user interface for
  task-level control of communication and domotics
  facilities

• As opposed to a functional based integrated
  system
• Interface and interaction concepts are targeted
  towards elderly
• Includes personalized assisted living services
  that fit into everyday life

6
Sub-goals

• Increasing acceptability and ease of use of
  autonomous networked home services
• Simplification of system and services development
• Enabling remote communication between care client
  care professionals and social network
• Enabling local communication between central user
  interface and appliances

7
Home Calendar Metaphor

• Central home calendar interaction metaphor
• Detection of routines based on user input and
  system awareness
• Home care services triggered at appropiate moments

8
Exemplary case

• Example of typical elderly home care client
• Anne, 70 years old, mentally healthy
• Limited mobility due to sight problems caused
  by diabetes
• Prefers to keep on living independently as long
  as possible
• Orders services from home care center
• Anne would like her family to be able to
  monitor her in case of
• home accidents
• Note Care, not Cure.

Exemplary case
service 1 personal alarm

service 2 remote support
Anne (client)
service 3 remote monitoring of routines
Service provider offers service bundles The
services offered to the home care clients by
service providers are based on the individual
care needs. A service can be a combination of
extra hardware (for example service 1 and 2 an
alarm button or an ECG monitor) and specialist
feedback (service 3 remote monitoring by a
medical specialist).
service 4 domotics (e.g., door lock opener)
10
Exemplary case
Services linked to calendar The services are
triggered by the adaptive calendar, and, vice
versa, the services can adapt the calendar. For
example, when Annes medical condition needs
extra attention, the calendar can be extended
with an extra monitor activity.

service 1 personal alarm
service 2 remote support
Anne (client)
service 3 remote monitoring of routines
End user interaction The central calendar based
interface provides Anne with a central access
point to the services. Anne uses her TV and
speech or remote control to control the system
and responds to system suggestions.
service 4 domotics (e.g., door lock opener)
11
Exemplary case
Calendar adapts to routines A central
personalized calendar monitors Anne, and the
calendar is updated accordingly. This way, for
example, a medicine reminder can be linked to a
eating breakfast routine instead of a fixed
timeslot. When Anne leaves home just before a
visitor arrives, the calendar reminds Anne of her
appointment.

Approach key elements

• Achievement of user-goals through collaboration
  between system and users
• Linking of care-services to domestic routines
• Dynamically updating of balance between system
  initiative and user control
• Modular and dynamic adaptation models as
  availability of services and devices is subject
  to change

13
Approach linking task, activity and routine
models to a calendar
ROUTINE BASED CONTEXT MODEL
AWARE CALENDAR
layer 1 domestic routines
context updates
layer 2 user activities
layer 3 tasks
triggers (suggestions)
layer 4 actions and statements
HOME CARE SERVICES
communication services
observed events and user dialog acts
domotics services
USERS
elderly user
care professional
remote contact
support services
